secured upon its outer projecting portion.

Adriving wheel-'5 is j'ournaled or mounted.

loosely upon that end of the shaft or spindle 3 projecting into the case 1-'.2,vv adjacentthe back of the case formed by the cup l, the wheel 5 being provided with a forwardlyor outwardly projecting rim or annularflange 6 which vis provided with an internal bevel gear 7 at lts forward or free edge. A spiral spring 8 is disposed Within the rim 6 of the wheel 5, andhas its endsv attached .to the said rim 6 and the forward end of the shaft 3, whereby .the spring 8 may be wound up by rotating the shaft 3 through the medium of the handle 4, as will hereinafter appear,v

As a means for operativel connecting the case 1 2 and han e 4, the ack of .the 4case is provided with an annular outstandingor rearwardly projeeting'fiange 9. surrounding the shaft 3 and the back ofthe casev isiurther providedwith an annular,- series of. ratchetteeth 10 disposed withinthe flange 9i and surrounding the shaft 3. Acup-shaped element 11 is applied tothe forward. end of` case to rotate readily relative to one another,

In order to'hold.the handle 4 andtheelement 11 against rotation on the shaft, the

shaftl 3 is rovided with keysl 12 engaged within the orward end of the handle 4: Mld within the slot 13 provided in the .element 11. Spring pawls or dogs 14 are secured. to the forward end of the handle 4 within' the cup-shaped element 11, screws orothersecuring members 15 being. engaged t rough the butt ends of thefpawls or dogs 14,'and

engaging through element 11. and Yintothe handle-4.l The.; awls or ,dogs '14 are of arcuate form, an have their free ends pro.

rotation .when the spring 8. is wqund up..

A; driving shaft or spindle 16 is journaled through the front plate 2 of the, case, eccentric ofthe axis of the-case and shaft 3. The forward end of the shaft or arbor 16 proljects beyond the front plate 3, andthe rear or; inner end of the shaft 16 is journaledthrough the freeend of an arm 17 of a: plate or member 18 attached to .theinnen or rearz face of the plate 2 adjacent the periphery ofthe. case. The shaft 4or spindlel isco'nnected by a train .of gears .to the gear wheel 5,A and to this end, a relatively small spur vforwardly and engaging the-annular series of ratchet teeth 10 to lock the shaft .3. and handle 4 .against retrograde. or reverse 'stub 25 attached to the inner face of the plate l2. The spur gear 24 intermeshes with a relatively large spur gear 26 having a bevel gear 27 attached to its hub and intermeshingwith the inner bevel gear 7 of the gear wheel 5, the hub of the spur gear 26 andl bevel gear 27 being journaled upon a stub 28 attached to the inner face of the plate 2. The train of gears 19, 20, 21, 23, 24, 26 and 27, serve to suitably increase the ratio ofrotation of the shaft 16 with respect to the gear'` wheel 5. It is to be noted lthat the train 4of gears is carried by the inner side of the front plate 2, in order that the gear train may be applied to the plate 2 prior to the assemblage of the plate 2 with the cup 1, and whereby when the plate 2 is applied to the cup 1, the bevel gear 27 will intermesh with the gearwheel 5 to operatively connect the gear wheel 5 and shaft 16.

As a means for controlling the velocity of and for arresting the movement of the shaft 16, a brake drum or wheel 29 is secured upon the shaft 16 between the spur gear 19 and the front plate 2, and a brake band 29a has one end attached to the arm 17 and partially surrounds the drum or wheel 29. The other end of the brake band 29 is attached to the inner end of the shank 30 of a button 31. .The button 31 is movable upon the periphery of the case 1 2, and its shank 30 projects through van arcuate slot 30a provided in the periphery of the case. A. double leaf spring or friction member 32 is attached to the inner end of the shank 30 and engages the interior of the case, to hold the button 31 at ,any position to which it is slid. Inasmuch as the shaft 16 is eccentric of the case, the movement of the button 31 will either loosen or tighten the brake band 298, as desired. As seen in Fig. 2, the button 31 is moved to the lower end of the slot 305' or toward the plate 18, whereby the brake band 29 is loosened to release the brake drum or wheel 29, but if the button is raised or moved to the other end of the s lot 30a, the`brake band 29a will be drawn taut and caused to frictionally gri-p the brake drum 29.` If the button 31 is at any intermediate position, the friction between the drum 29 and brake band 29 will be varied, to thereby vary the velocity of the shaft 16 when it is rotated by the spring 8.

The outer or forward end portion ofthe shaft 16 is adapted for driving various in` struments, such as a fan, a rotary safety razor, a massage implement, and the like.

As illustrated in the drawing, 'the implement is in the form of a fan 33. The fan 33 may be taken torepresent any suitable rotary implement. 1n applying the'implement 33 to the spring motor, a guard or cage 34 of any suitable character, according to the implement 33 employed, is provided, so as to surround and protect the implement 33. rlhe guard or cage 34 includes an inner ring 35 which is threaded or otherwise engaged upon an annular eccentric flange 36 formed upon the front face of the plate 2 and surrounding the shaft 16. The hub 37 of the implement 33 is preferably elongated, and has its outer end closed and rounded, the hub 37 being slipped over the forward or outer end of the shaft 16l and having an open slot or keyway 38 at its inner or rear end which engages a key or lug 39 provided upon the shaft 16 adjacent the plate 2,

whereby the implement 33 will be constrained to rotate with the shaft 16. The front of the cage or guard 34 is provided with a bearing 40 adapted to wat against the outer end of the hub 37 to maintain the hub in position upon the shaft 16, without impairing the rotation of the implement 33.

In applying the implement 33 and guard 34 to the case' 1 2 and shaft 16, it being understood that the implement 33 is.dis posed within the guard 34, the guard is moved over the shaft 16, and the hub 37 of the implement 33 is simultaneously slipped over the shaft 16. The ring 35 of the guard 34-is then/engaged to the flange 36 of the case 1 2, and the bearing 40 of the guard 34 in contacting with the outer end of the hub 37, will force the hub inwardly and in this manner the slot 38 of the hub may be engaged to the lug or key 39 of the shaft 16. The bearing 40 of the guard or case 34 will thus hold the implement 33 in position upon the shaft 16, as long as the guard or cage 34 is attached to the plate 2. As soon as the guard 34 is detached from the plate 2, the implement 33 may be slipped out of engagement from the shaft 16, for the substitution of a razor, massage implement, or the like, having a hub 37 similar to the fan 33 above described. It is of course understood, that when a razor, massage implement, or other implement is employed, the guard or cage 34 therefor must be of corresponding formation.

To wind up the spring 8, the case 1 2 is held by one hand, and the handle 4 is properly rotated by the other, the brake band 29 having been previously tightened, to 'hold the shaft 16 against rotation. Thus, the gear wheel 5 will be held stationary, during the winding up of .the spring 8, and the pawls or dogs 14 carried by the forward end of the handle 4, in engaging the ratchet teeth 10, will lock the handle 4 against retrograde or reverse rotation when it is released released from the drum 29, the implement 33 will be permitted to rotate at its full speed, whereas if the brake band 29 is frictionally en aged moreor less with the drum 29, the ve oclty of the shaft 16 may be reduced, or completely checked or arrested.

From the foregoing, taken in connection with the drawing, the advantages and capabilities of the present machine will be obvious to those versed in the art, without further comment being necessary, noted-that the objects aimed at have been carried out satisfactorily by the provision of the peculiar structure herein disclosed.
